it takes a very long time for things to go to press through
marketing from engineering so consider them preliminary

next  should say decrement R to -1 then drop R, not decrement to 0
-if   should say jns jump if no sign, ie. msb of T is false
-     should say ones complement of T not A, -1 XOR, NOT
drop;  drop

It is preliminary, but not quite as preliminary as Chuck's
paper from 2001.
